Quantification of the p 24 fusions accumulated in transgenic tobacco. Total proteins were extracted from leaves of plants expressing the indicated constructs. The amount of total extract indicated in each lane (in μg) was analyzed by SDS-PAGE and western blot with p24 antibodies. Each panel (A, B and C) is derived from a western blot in which also the indicated amounts (in ng) of recombinant, pure p24 were loaded as a reference. Numbers at left or right indicate the positions of molecular mass markers, in kDa.
